I'm just wondering is there any way to add more than one message into the chat.
Just do the chat twice:
-- This has to be a LocalScript function chat(text) game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage",{ Text = text; Color = Color3.new(255,255,255); StrokeColor = Color3.new(0,0,0); Font = Enum.Font.SourceSansItalic }) end for i =1,2 do if i == 1 then chat("Text1") elseif i == 2 then chat("Text2") end end
